We study radiative transfer through a weakly polarizing medium, i.e., a medium in which the degree of polarization of the absorbed, retarded, and emitted light...
We present very fast radiative transfer tools of interest for the interpretation of future spectroscopic observations taken with the GTC and its post-focus...
Radio emission in a nearby, ultra-cool dwarf binary: A multifrequency study
Context. The substellar triple system VHS J125601.92−125723.9 (hereafter VHS 1256−1257) is composed of an equal-mass M7.5 brown dwarf binary and an L7 low-mass...
Radio spectrum evolution and magnetic field in extreme GPS radio sources. The case of RXJ1459+3337
Aims:The knowledge of the properties of the youngest radio sources is very important in order to trace the earliest phase of the evolution of the radio emission...
Supernova 1993J (SN 1993J) in M81, now classified as Type IIb, is a strongly emitting radio supernova whose size can be resolved and whose growth can be...
Rapid timing studies of black hole binaries in Optical and X-rays: correlated and non-linear variability
In a fast multi-wavelength timing study of black hole X-ray binaries (BHBs), we have discovered correlated optical and X-ray variability in the low/hard state...
Rayleigh-Taylor instabilities with sheared magnetic fields in partially ionised plasmas
Aims: In the present study we investigate the nature of the magnetic Rayleigh-Taylor instability appearing at a tangential discontinuity in a partially ionised...
Rayleigh-Taylor instability in partially ionized prominence plasma
We study Rayleigh-Taylor instability (RTI) at the coronal-prominence boundary by means of 2.5D numerical simulations in a single-fluid MHD approach including a...
Rayleigh-Taylor instability in prominences from numerical simulations including partial ionization effects
We study the Rayleigh-Taylor instability (RTI) at a prominence-corona transition region in a non-linear regime. Our aim is to understand how the presence of...
